1 inch to 4 feet: 8 inch^2 to 128 feet^2
1 inch to 5 feet: 5 inch^2 to 125 feet^2
1 inch to 3 feet: 13 inch^2 to 117 feet^2
1 inch to 2 feet: 12 inch^2 to 48 feet^2

When converting square units, you have to square the original conversion rate. For examples, if 1 inch equals 4 feet, 1^2=1 square inch equals 4^2=16 square feet. Do this for each conversion above.
